Peer-to-peer custom device only works on the PXIe-8821.

Peer-to-peer custom device only works on the PXIe-8821 CPU. We have a custom device for peer-to-peer communication between the FPGAs. This works with the PXIe-8821 CPU,
but if I install the PXIe-8862 or PXIe-8881 CPU with the same way as the 8821, no data is transferred peer-to-peer.
Do I have to consider the type of the custom device in the Custom Device project? I've only entered an RT PXI Linux X64 target without a specific type.
Does anyone have any ideas?

What version of driver are you using?

The only difference between these controllers I can think of is the minimum PXI Platform Service version.

Perhaps you can try if these hardware combination can work in pure LabVIEW ADE?

The latest PXI Platform Service driver, 23.8, is already installed. It's the same on both.
